Mathematics (2019) Grade(s): 3

MA19.3.26

Recognize and describe polygons (up to 8 sides), triangles, and quadrilaterals (rhombuses, rectangles, and squares) based on the number of sides and the presence or absence of square corners.

UP:MA19.3.26

Vocabulary

  • Attribute
  • Category
  • Sub-category
  • Opposite sides
  • Angles
  • Quadrilateral
  • Triangle
  • Pentagon
  • Hexagon
  • Septagon
  • Heptagon
  • Octagon
  • Polygon
  • Square
  • Trapezoid
  • Rhombus
  • Rectangle
  • Two-dimensional

Knowledge

Students know:
  • that shapesin different categories may share attributes and that the shared attributes can define a larger category.

Skills

Students are able to:
  • Identify two-dimensional shapes.
  • Sort shapes according to number of sides.
  • Sort quadrilaterals based on the presence or absence of square corners.
  • Draw examples of squares, rectangles, and rhombuses.
  • Draw quadrilaterals that are not rhombuses, rectangles, and squares.

Understanding

Students understand that:
  • Attributes of a shape help make decisions about how to categorize the shape.
  • Certain attributes are needed to belong to the subcategories of rhombuses, rectangles, and squares.
  • Sometimes a shape does not have the attributes needed to belong to the subcategories of rhombuses, rectangles, and squares.
Mathematics (2019) Grade(s): 4

MA19.4.27

Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines, and identify these in two-dimensional figures.

UP:MA19.4.27

Vocabulary

  • Point
  • Line
  • Line segment
  • Ray
  • Right angle
  • Acute angle
  • Obtuse angle
  • Perpendicular lines
  • Parallel lines
  • Two dimensional figure
  • Vertex
  • Angle measure

Knowledge

Students know:
  • defining characteristics of geometric figures, such as points, lines, line segments, angles (right, acute, and obtuse), parallel lines, and perpendicular lines.

Skills

Students are able to:
  • Draw points, lines, line segments, rays, angles (right, acute, obtuse).
  • Draw parallel and perpendicular lines.
  • Identify points, lines, line segments, rays, angles, parallel lines, and perpendicular lines in two-dimensional figures.

Understanding

Students understand that:
  • points, lines, line segments, angles (right, acute, and obtuse), parallel lines, and perpendicular lines are defining characteristics of two dimensional shapes.
Mathematics (2019) Grade(s): 4

MA19.4.28

Identify two-dimensional figures based on the presence or absence of parallel or perpendicular lines or the presence or absence of angles of a specified size.

UP:MA19.4.28

Vocabulary

  • Two-dimensional figure
  • Parallel lines
  • Perpendicular lines
  • Angle
  • Right triangle

Knowledge

Students know:
  • Two lines are parallel if they never intersect and are an equal distance apart.
  • Two lines are perpendicular if they are at right angles to each other.
  • A right triangle is a triangle that has one right angle.

Skills

Students are able to:
  • Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines.
  • Classify two-dimensional figures based on the presence or absence of angles of a specified size.
  • Identify right triangles.

Understanding

Students understand that:
  • shapes are categorized based on attributes they possess in common such as angle size, side length, side relationships (parallel and perpendicular).
Mathematics (2019) Grade(s): 5

MA19.5.22

Classify quadrilaterals in a hierarchy based on properties.

UP:MA19.5.22

Vocabulary

  • Quadrilateral
  • Hierarchy
  • Two-dimensional
  • Properties
  • Attributes
  • Polygon
  • Rectangle
  • Rhombus
  • Square
  • Trapezoid
  • Parallelogram

Knowledge

Students know:
  • properties or attributes of two-dimensional shapes.

Skills

Students are able to:
  • Classify quadrilaterals based on properties.

Understanding

Students understand that:
  • Quadrilaterals can be identified by general properties to more specific properties.
  • Properties belonging to a category of two-dimensional figures also belong to all subcategories of that category.
